Atmel Smart RF
Atmel offers a broad range of integrated circuits for
a variety of RF applications in the ISM bands. The
product portfolio includes single-channel transmitter
ICs, receiver and transceiver ICs, as well as multi-
channel transceiver circuits and transmitters with an
integrated MARC4 4-bit or AVR microcontroller.
®
The frequency range spans from 250-450 MHz to
88-870 MHz, 902-928 MHz and 2.4 GHz, thus
enabling all kinds of applications in the industrial
and consumer area.
All Atmel ISM products provide a high integration
level and enable easy implementation.

System Solutions
An ISM system consists typically of at least two
RF nodes. The most simple system has a transmit-
ter on one side and a receiver on the other side.
For many applications such as remote controls for
lights, garage doors, air conditioning systems etc.,
this is sufficient.
For mobile or handheld end products, a highly in-
tegrated system allows the manufacturing of very
small transmitters. This solution is based on one-
way communication, but using a micro-transmitter
on the transmitter side.
Two-way communication systems may have a very
simple link with low data transmission rates, but high
The system diagram shows a typical one-way link
application with an AVR

micro-transmitter. By
replacing the transmitter and the receiver by a
transceiver on each side, a two-way communi-
cation system can easily be designed.
data rates of up to 1 Mbit/s as required for wireless
data transfer, control or gaming are also possible.
